Digital Information
Unit EQ: How do computers make students or employees more productive
LEQ: Is the transistor the greatest invention in the last 50 years?
Activating Strategies: take out paper and list things that have transistors in them?(link to video)
Acceleration/Previewing/Vocabulary: Write a sentence using the following words: Digital, Binary, Analog, Information. Call on 2 students.
Teaching Strategies and Distributed Guided Practice/Summarizing Prompts:
  1. Check Math Lab Homework

Digital Information

Digitial vs Analog * Analog, varying voltages, volumes, rotations

Microprocessors: Transistor is a switch without moving parts.
  • Fetch, Decode, Execute Mention how math lab shows how slow we are!
  • Transistors are made from silicon. Silicon is a semiconductor. A material whose conductivity can change.
  • Scale of Transistors : How big is a human hair? About 100 microns in diameter. That means a transistoris just 0.045 microns wide. Transistor Timeline
    Digital Information
  • Binary Code
    • Bits zeros and ones
    • show CAT binary overhead slide
  • Pixels(video)
    • Dots in a digital image.
    • Show rollerblade overhead
